Abstract

L'invention concerne un procédé de détection de matière nucléaire dans un objet étudié par interrogation neutronique avec un tube à particule associée, le procédé comprenant des étapes de détection d'impulsions en coïncidence par des pixels détecteurs d'au moins une matrice de pixels détecteurs, une étape de détection d'impulsions en coïncidence conduisant à la formation d'un événement qui traduit une fission qui survient dans la matière nucléaire, le procédé comprenant une recherche de pixels voisins parmi les pixels qui ont détecté des impulsions en coïncidence, un regroupement des pixels voisins par groupes de pixels voisins, un comptage des pixels et/ou groupes de pixels voisins qui ont détecté des impulsions en coïncidence, et une validation de survenue d'un événement dès lors qu'au moins trois pixels et/ou groupes de pixels voisins sont comptés.The invention relates to a method for detecting nuclear material in an object studied by neutron interrogation with an associated particle tube, the method comprising steps of detecting pulses in coincidence by detector pixels of at least one matrix of detector pixels , a step of detecting coincident pulses leading to the formation of an event which reflects a fission which occurs in nuclear matter, the method comprising a search for neighboring pixels among the pixels which have detected coincident pulses, a grouping neighboring pixels by groups of neighboring pixels, a counting of the pixels and/or groups of neighboring pixels which have detected pulses in coincidence, and a validation of the occurrence of an event as soon as at least three pixels and/or groups of Neighboring pixels are counted.
